Cooperative manipulation of a floating object by two underwater robots with arms

In future ocean development, it is considered that many tasks will be achieved by cooperative motions of several underwater robots. However, no research has been studied on the cooperative work of underwater robots. We have proposed a cooperative control method for space robots. In this paper, as the first step of development of cooperative control methods for underwater robots, our proposed resolved acceleration control method for underwater vehicle-manipulator system is applied to cooperative manipulations of a floating object by underwater robots. To validate the control method, computer simulations are done. The simulation results show the effectiveness of the control method.
